OK, help me out with this patch.

I thought it was necessary to calculate a from starting offset based on
mtd size and nvram size since the code assumes the nvram partition might
not start at 0 whereas in the patch it looks like a 0 starting offset is

When I was working on this area of code, IIRC, the from offset was
actually not 0.
